Question

Why 2nd electron affinity is positive ?

Answer 1

The 2nd electron affinity is defined as the enthalpy change for: Because the electron is negatively charged you can see that there will be repulsion between the ion and the electron making the process endothermic, hence the positive value.

However, more energy is required to add an electron to a negative ion (i.e., second electron affinity) which overwhelms any the release of energy from the electron attachment process and hence, second electron affinities are positive
